pinion gearbox
A Pinion gearbox drivetrain on your mountain bike might be the right fit for you if you like to ride silent, extremely smooth and smash your derailleur regularly.

A low center of gravity gives the Kodiak excellent handling and unparalleled riding dynamics. But the gearbox also offers minimal maintenance and a superior, perfectly graduated gear range.
The unsprung mass of the rear wheel is a lot less, as a derailleur and cassette are no longer needed, they are replaced by the gearbox in the center of the frame. This results in a responsive, lively ride feel and more grip on any trail surface, no matter how rough.
The Kodiak is a Pinion gearbox mountain bike specially made for your next cycling adventure. Whether touring for several days, riding technical trails or racing in a demanding enduro stage.
chain or belt
If you want even less maintenance and a perfectly silent ride, you might consider riding with a belt drive. The chain is then replaced by a carbon belt, which is only possible in combination with a gearbox drivetrain.
You can choose to ride the Kodiak 130, Kodiak 140 and Kodiak 150 with chain or carbon belt drive. The Kodiak MX 150 only comes as a chain version.
Riding a carbon belt is a little less efficient at transferring power. So if you participate in races or ride extremely muddy trails, you better go for the chain option.
next level riding
Experience the quick line selection, railing corners and increased stability in technical sections.
The central positioning of the gearbox in the frame reduces the unsprung mass and increases rear suspension sensitivity. This results in a responsive, lively ride feel and increased grip on every trail surface, giving your maximum confidence.
Pinion’s magnesium gearbox is almost maintenance free and eliminates the risk of bending or breaking your derailleur.
chain drive
All our gearbox bikes come with a chain drive. We have done tests with belt drive, but most of our riders later made the conversion back to chain, as it feels more active, more efficient and works perfectly under all circumstances.
fast shifting
A Kodiak gearbox mountain bike can be equiped with either the Pinion DS2 grip shifter, the Pinion Smart.Shift or with an Instinctiv trigger shifter. In all cases; shifting is very fast, instant and precise.
The Instinctiv Trigger Shifter offers an interaction that is resembling a derailleur shifter with the speed of a gearbox. The system has two stacked levers for thumb actuation. It allows you to shift one gear heavier, or one or two gears lighter with a single thumb stroke.
electronic shifting
Pinion Smart.Shift electronic shifting is very quick and precise with a push on the button.
The shifting battery is fully integrated into the Kodiak frame, from the outside you hardly see there is an electric shifting system on board. The Smart.Shift gearboxes differs from the normal C line gearboxes in their internal structure. The shifting mechanisms and sensor technology are the main differences, so you can not add Smart.Shift to a normal Pinion gearbox.
600% range
With 600 % range and evenly spaced gear steps, a Pinion gearbox mtb leaves derailleur bikes in its dust.

efficiency
What happens to the watts you put out? How does a Pinion gearbox mountain bike compare to a conventional derailleur in terms of efficiency?
The short answer is that out on the trail, in varied terrain and changing conditions, it is practically impossible to notice any difference.
A derailleur layout, under perfect ‘laboratory’ circumstances, has a bit higher efficiency. However when dirt comes into play and builds up the efficiency tends to drop a good few percent.
A major benefit of Pinion gearbox mountain bikes is the straight, constant chainline, ensuring great efficiency between chainring and rear wheel.
weight
Yes, a mountain bike with gearbox weighs about 600 – 800 grams more than a bike with a conventional 1×12 derailleur groupset.
But about 600 to 900 grams of weight is moved from the rear wheel to the center of the frame. This makes the rear wheel lighter and makes the suspension respond better. And during a climb, the extra weight is hardly noticeable.
less maintenance
A Pinion gearbox on your mountain bike means more time on the trails. The gearbox operates in an open bath and is self-lubricating, so you only need to change oil every 10.000 km. You have almost no drivetrain maintenance and high cost of replacement parts.
The Pinion gearbox is integrated into the frame at the bottom bracket and is completely sealed from the elements. It is protected from water and dirt and performs in all weather conditions. When the going gets rough on the trail, there are no visible shift components that can break off if you go a little too far.
